Our Awesome Clients
Find high-quality Plastic Injection Molding Services?
How To Work With Us
The plastic injection molding process may seem simple, but there are many parameters that need to be tightly controlled to ensure the quality and consistency of the plastic components produced.
Submit Request
To obtain a complimentary quote, please provide a product description and technical drawing with your request. Don’t have a technical drawing available? Not a problem. We offer reverse engineering services as well.
DFM & Quotation
Our typical response time is within 24 hours. However, please note that the communication process may require ongoing discussions, and the entire process is completely free of charge.
Mold Making & Molding
Once the design has been approved, we will start making the mold for your plastic parts. Our team will use advanced technology and equipment to fabricate a high-quality mold that meets your specifications.
Post Treatment & Reliable Delivery
Once the mold is ready, we will begin the injection molding process. Our skilled technicians will use the mold to create high-quality plastic parts consistent in shape and size. We will perform quality control checks throughout the process.
Tolerance
Factors that influence the tolerances of injection molded parts include material properties, product design, mold design, and the injection molding process. When determining tolerances, it is important to balance the appearance and functionality of the finished product with overall cost considerations.
Gdzycnc typically follows the DIN 16742 standard for injection molding tolerances. For automotive applications, we comply with the QC/T 29017-1991 automotive industry tolerance standard. When customers have specific tolerance requirements, we strictly adhere to their specifications.
The Plastic Injection Molding Process
1.Clamping
The core and the cavity are the two main pieces of an injection mold. In the first step, during clamping, these two parts of the mold will be extruded and fit together by the machine.
3. Dwelling
Next is the dwelling phase, where the melted plastic is filled to the entirety of the mold through pressure. The pressure is applied directly to the mold such that the liquid fills all mold cavities, and the product comes out accurately and is identical to the mold.
5. Mold Opening
This is the opposite process of clamping. In this step, a clamping motor slowly opens the two parts of the mold to make for the safety and stability.
2. Injection
The plastic pellets are fed to the part of the barrel and loaded into the main cylinder, where they are heated at high temperatures to a liquid. The plastic liquid will be injected into the mold cavity when mixed in good condition.
4.Cooling
This process step allows the time needed for the mold to cool. If this step is performed too hastily, the products may stick together or become distorted when demolding.
6. Ejection
After the mold is opened, the ejector pin will push the cooled product out of the mold cavity according to the design position, so that a basic product is completed.
